If you want to dilate an isosceles right triangle with a hypotenuse of 18 yards, to create a dilated image with a hypotenuse of 12 yards, what scale factor should you use?

Answer 1

To find the scale factor, we need to compare the lengths of the original hypotenuse (18 yards) and the dilated hypotenuse (12 yards).

Scale factor = dilated hypotenuse / original hypotenuse
Scale factor = 12 / 18
Scale factor = 2 / 3

Therefore, the scale factor to dilate the isosceles right triangle with a hypotenuse of 18 yards to create a dilated image with a hypotenuse of 12 yards is 2/3.
